10 ((17 "whom it may concern:

New Jersey, have invented certain new and useful Improvements in Eyeglasses, of which the following is a s ecification.

My invention re ates to improvements inv eyeglasses; and one object of my invention is the provision of an eyeglass which will adapt itself or perfectly fit the nose of the wearer and which will at all times retain the lenses in the proper position or parallelism with reference to the eyes.

Another object of my invention is the provision of an eye lass which cannot possibly become detacher l and in which rattling or loosening of the parts is entirely prevented.

Another object of my invention is the provision of an eyeglass which will be of simple, inexpensive, and durable construction and which will be thoroughly efficient and practicalin every particular.

With these objects in view my invention consists of an eyeglass embodying novel features of construction and combinations of parts, substantially as disclosed herein.

In order that the details of construction and the operation of the parts of my device -may be fully understood and its many advantages be appreciated, I invite attention 1 edge view of the eyeglasses, dotte to the accom anying drawings, which illustrate an eye ass constructed in accordance with and emhodying my invention.

Figure 1 represents a rear elevation of theeyeglasses. Fig. 2 represents a front elevation. Fig. 3 represents a top plan or top lines showing the position of the glasses when ap lied to the noseof the wearer. Fig. 4 is a etail view of the brid e or bow spring of my device to particularly illustrate its peculiar and novel construction, the views showin said sprin before the coils or loops have een forme therein. Fig. 5 represents a detail view of the bridge orbow sprin with the coils or loops formed therein. Eig. 6 re resents a detail view of one of the nose-guar s. Fig. 7 represents a detail view of one of the noseguards, the intermediate bearing-plate, and one end of the bow or bridge spring; and Fi 8 represents a detail view of the disks or a s carried by the nose-guards-and which upon the nose.

In the drawings the letter A designates the lenses.

B designates the nose bridge or bow spring, formed with the coils C C and terminating in the horizontally-disposed ends D, having an opening E to receive the fastening F for at taching the plates or ends to the lens and also provided with the opening G to receive the screw H, which connects the intermediate plate J, having the lips K, which rest against the edge of the lens, and the fastenings F and H also serve to connect the nose-guards L to the lens and to the bridge-spring and the intermediate plate. The nose-guards have their depending portion L tapered toward their lower end, to which lower end is connected the flat springs M, to which at the u per end are connected the nose pads or disl s N. Said nose-pads ma be loosely connect ed to the upper ends 0 said springs or may be rigidly secured, and an important feature of these pads is their peculiar elliptical sha e or egg shape, as this construction insures t e pads gripping the nose more firmlyand preventing the eye lasses from detachment or from becoming isarran ed.

It will be observed t at the flat bow or bridge spring is arranged at an incline or obliquei y with reference to the lenses, this caus ing the glasses to fit the nose more perfectly and also to give a better appearance, and the spring, as shown in Fig. 4, is formed with the reduced or thin portions 0, from which the coils and loops are'formed, and the particular advantage of this construction is that the main or central portion of the spring remains comparatively rigid, but the coils or loops can be easily sprung to suit the circumstances and to insure a greater amount of resiliency at the coils and a erfect fitting of the lenses upon the nose. he coils of said spring are to be formed-substantially as follows: Beginning at the innermost end of either stud the thin ortions are to be bent first rearwardly, then engthwise on a plane with the lenses,- then outwardly, then upwardly and'over the first bend in the coil, then lengthwise on a plane with the lenses and forming a complete oo or coil. either of oval or circular shape, an being artially obscured from sight when looked at rom'the front, and this construction is an important feature, as it adds'to the attractive ap earance of the mounting. It -will also be'o served that the intermediate bearing-plates J are formed so as to present their thin edges to the edges of the lenses and are stamped out of stiffened metal. In the constructions now common in use the studs are formed of three pieces of metal brazed together, causing the metal to become soft and easily bent, and the lips or flanges of said studs present their broad sides to the edge of the lenses and being of soft material consequently are easily bent by the leverage exert: ed by the lenses in adjusting the glasses to the nose, thus losing the perfect alinement of the lenses. My construction avoids these disadvantages and supplies a most desirable and necessary adaptation of the devices, and another important feature of these bearing plates is that when the parts of the glasses are put together they are pivoted between the nose-guard and the ends of the spring and that the lips of said bearing-plates ad just themselves to the fit of the edges of the lenses and prevent chipping of the edges of the glasses when being inserted into the studs, and when the parts are secured to ether a perfect fitting oi the plates a ainstt e edges of the lenses is insured, and t is is a very important feature, as in connection with the other features orparts of my eyeglass rate tling of the parts is absolutely revented. It will also be observed that the epending por tions of the nose-guard are tapered toward their lower ends, which gives the strongest portion of said ends at the upper portion or uncture with the horizontal attaching portion of the noseguard, and this is also an in portant feature, as it makes the ards strongest at'thepoiht of great strain.-

will also be observed that the peculiar egg shape springs enables the disks to be either secured rigidly or loosely and that the egg shape sures a erfect engagement of the disks with the cuticle of the nose and absolutely prevents displacement or movement of the lenses upon the nose.

Another feature of importance in my 'invention is that I dispense with the studs or boxes in general and common use and make the horizontal ends of the spring and the horizontal portions of the nose-guards in connec tion with the intermediate plates form studs or connections of the parts with the lenses,

1 and by my construction the lenses are always retained in the proper arallel' and vertical position, and it is abso utely impossible for the parts to work loose or become detached,

and rattling is thus absolutelyiprevented.

. The egg-shaped or oblong nose-ipads are fastened at their innermostends, or as near as practicable thereto, by means of one oval or oblong pivot or by two separate rivets in order to maintain the horizontal plane of said nose-v ads, the nose-pads to be rigidly or', loose y pivoted, so that any movement-of the cuticle of the nose or jar or gust of wind will not dislodge the glasses from their position on the nose. Anovel and important feature sea-n17 in the said disks is their oval or oblong sha e and being fastened at their innermost en s The advantage oi. this construction is that the outer or long ends will take a deeper hold or engagement on the cuticle of the nose, and should perspiration on the nose cause the glasses to slide forward the eculiar construction will cause the long en to exert its pres sure at the outermost end of said disks or pads, causin the cuticle to rise in front of 7 said long en and cause a firm engagement and prevent forward movement upon the,

' termediatebearing-plates, means for connect-1 ingthe nose-guards and bearing-plates and for securing the nose-guards and spring to 1 the lenses, said how or bridge spring being formed with coils or spring-loops of thinner material than the body oi'the spring.

2.. An eyeglass consisting of the lenses, the bow or bridge spring arranged obliquely or at an incline to the lenses and having the "coils or loops of thinner material than the body portion and terminatingin the horizonj tal portions arranged in line with the horizon- 2 tal ends, the nose-guards having the horizon l tal ortion of the spring, the plates having the ips fitting against the edges of the lenses. of the disks or pads carried by the nose-guard w of the"nose guards and s ring, and the fasi tenings for corinEctin tions of the spring an nose-guards with the and located between the horlzontal portions t e horizontal porlens and the fas'tenings for connecting the intermediate plates with said horizontal portions of the spring and nose-guard.

, 3. A11 eyeglass consisting of the lenses, the bow or bridge spring having its main or central portion arran ed at an incline to the lenses and provide with the spring coils or IOC loops of thinner material than the main portion thereof and terminatin in the horizontal ends for. attachment wit the lenses, the

nose-guards havin the horizontalportions attached to the ot er side ofthe lenses and "having the dependingv tapered end, the

s rin s connectedto the guards 'and'carrying the egg-shaped nosepads, and theintcrm'ediate bearing-plates fitting ,against the lenses and having aportion connected with the hori' zontal portion of the nose guards and spring;

In testimony whereof I aflix 'my signature" in presence of two witnesses.
